To 1777 whom "it may concern lic it known that "l, llnnnx' J. NEUM'I-LIS- 'll-Zll. u citizen of the United Stains, and a rcsidcnt o1 (hicugtu in the county of Cook unrlflohit'e ot Illinois, have invented certain new and uoe'tiul improvements in Combined. Quick-Detznchuhlo Couplings and Valves; and I do horeliy declare that the following is u full, elem; iuul evict description thereof re'tcrenco heing llzlil to the .ucconipunyin; drawings, :uu'l to the churzn'rters o'l reference nuirheil thereon, which form a part of this s wcil'ieution.

This invention relates; in lITlPlOVtJlllOtlliFi in coinhinctl quick lletnehxihln hose. couplings and wives, and refers morn specifically to that type of valve and coupling in which the coupling monilier oi the valve forzncxl or nnu'lo a part of the Volvo movement; ol which opens and closes tho vulvc.

The lllVl'tll'lOll consists in the matters heroinultcr nob forth and. more particularly print-oil out in the appended claims.
